'To'aZZ-whomit may concern: I

Be'it known that I, ABRAHAM SMITH, a citizenof the United States, residingPat Erie, in the county of Erie and State of ennsyl- Vania, have'invented certain new and useful Improvements in Computing and Recording Machines and I'do hereby declare the'follo'wiiig to be a full, clearfl'and exact description of the invention, such as will enable others skilled in the artfto which it appertains toiinake andfn'sei the same, reference being had to -the1 aco0inpanj*ing'i'drawings, and to the letters of reference,marked'thereon, forming part of this specification.

' "This invention relates to'coinputin'g machines which are adapted to 'add and subtract and -record .the items added or sub 'tracted, together with the vtotalsan'd remainders,"-andj eit-her retain the total and remainder in the accumulators, or leave them at zerofl n One object ofmy invention is to provide a computing machine withtwo driving racks chine the gear wheel is never disengaged, or

disenmeshed from one or the-other rack.

Another object of my invention is to providea single accumulator for each numerical order which is coupled to the rotary detent member, and which will be operated from the same point of engagement for either' addition or subtraction, and which will be interlocked during disengagement.

Another object of my invention is to construct a computing machine in which subtraction, is effected by reversing the movement of the accumulator without reversing the movement of the printing mechanism.

Another object of my invention is to provide in such a machine, a transfer or carrying-over mechanism which is actuated dircctlv by the accumulator wheels. and the operation of which is identical in either addition or subtraction.

In carrying out these objects of invention, l have constructed. a computing ma hine in which the type carriers and aruun'i atuis are controlled by rack and gear driven i jcoiirnrmonnn RECORDING MACHINE.

. Specification of Letters Patent. Patented Aug. 22, 1922.

1920. Serial No. 381,875.

rotary members, and depressible hey-stops, in which the operation of direct subtraction is affected by shifting the gears Without changing the position of the accumulator or the type carriers, the mechanism being so constructed that the gear wheels do not become disengaged ordisenmeshed from the racks, but during the shift over-lap a pair of racks, so that the racks and gears are locked until the shift is completed.

I will set forth in a general way the plan jof'my invention, '-viz:

. r Pidnting mechanism.

The printing mechanism consists of a series of type levers pivoted in the frame of the machine. On each of said levers there is a segmental type carrier, which has type mounted thereon in the usual manner. There are individual springs to raise said ty elevers upwardly, and main spring mec anism adapted to enga e said type-levers and force them downward against the action of said individual springs.

Actaati ng mechanism.

The actuating mechanism of my machine is a rockshaft transverselymounted in the machine, and provided with a crank or other means for operating it. The initial movement of said rock-shaft to the right removes the tension of the main-spring mechanism from the type-levers and permits them to be raised by their individual springs, and the return reverse movement of said rock-shaft releases the tension of the main-spring so that it can force said type-levers to return to their normal position against the action of their individual springs:

(M n-trolling or selective mec/autism.

'lhemcchanism of my invention by means of which the upward movement of the typelevers is limited at certain elevations so that the desired type carried by the several type levers will stop atthe printing line at the will of the operator, consists of gear-racks which are caused to more verticallv by the individual springs of the type levers, pinion gears intermeshing therewith to rotate members which carry detents, and key-board nurchanism adapted to be engaged by the zletcuts on said rotary members when the lccvs 1. re depressed. so that when the actuatnamrhanir-gm is operated the individual springs of the type-levers raise their respective racks and cause the detenl-hearing memhers to rotate until a detent thereon engages and is stopped by the mechanism of a depressed key, which thereby limits the upward movement of its respective type-carrier at the point where the type, corresponding-to the keydepressedwillj be at the printing line on the platen roller.

Key-board mechanism.

The hey-board, mechanism including the keysv and; indiyidual-vlrey-locking mechanism .isassemhled in a removable frame, which can be bodily placed in the machine and re movedtheretro without disturbin the rest of the machine or disassemblin o the keyboard. The keysr arranged n;. l andare numbered. from 1 to.9,- in the ,well known order. The keyboard; mechanism is rov'rded with means. whereby. any depress d key is retained in itsidepressedposition irom which it is released by depressing a second key in the same column,- or by theoperation of the. a ctuating rnechanism.

' Accmniilating means.

Mountedinthe machine is a series. of accumulating mechanisms which are actuated by, the rotary; members and areadapted to record. the respective results of the. operations, Of addition .01: subtraction. The accumulating mech nism also, through. the agency of the rotary mernbens, actuates and controls the printing mechanism to record the results of'the'operations of additions or subtractions, when desired.

, I il mmfenor caa-wmgwver mChdltZSflt.

I, provide a series. of bell-crank levers, onB. arm of each lever bein adapted to be engagedby a. cam on each 0 the accumulatniechanisms, each of said levers having pivoted to the other arm thereof a horizontally. movable bar which extends rearwardly the machine where it controls the rack bar, mechanism'of the next higher order, so that when the accumulator of the lower order has made one revolution the said horizontally movable bar is moved to permit the rack of the next higher order to drop sufliciently tov cause the rotary member geared. thereto to turn its associated aceumu later oneunit.

These. and other features of my invention are hereinafter more fully explained and pointedout and are illustrated in the accompanying drawings in which:

In these drawings A indicates the baseplate (see Fig. 7) and A A indicates side- Pmting mechanism.

Upon a transverse shaft B, secured and supported by the side plate A, are mounted a series of levers B, B B B, B, B and B", each of which carries on its free end segmental type carriers 1), said levers being provided with individual retracting springs 1) adapted to raise said levers B, etc. when the same are released, as hereinafter described. .The levers B, etc., are provided with means v for moving and maintaining said levers in their normal downward position, as shown by full lines in Figs. fifand 12, consisting preferably of arms b which are engaged by a laterally movable crossbar C; and I provide main-springs C or other form of spring vmechanism,.whicl 1 are adapted place. sufficient tension on; the cross-bar to-force the sameagainst the arms 1 b ,with suflicient'. force to overcome the .tensiouof the individual springs b and force all the type levers B, etc., to their lowermost position in whichthe are normally retained, by the cross-bar when the machine is not operated.

Acmatz'ng mechanism. Mounted in the side-plates A. A is a transverse rock-shaft D,- (see Figsl, 2, 3, G and 8) which is provided with anoperating crank D; secured on said rock-shaft D are cranksD from the free ends of which link bars D extendto short-levers d which are rotatablymounted on the shaft (1', supported in upright supports A A secured on the base of the machine; said levers d being provided with arms oi which overlap levers C also mounted on the "shaft cl, beside the levers d; and from the free ends of the levers C rodsc extend'forwardly and are secured to the transverse bar C so that when the rockshaft D is rotated a. quarter turn toward the right, the levers D through the link bars D and levers d and G on the shaft d and rods 0, move the transverse bar Q rearwardly against the action of the, main-springs C, which ermits the individual 3 ringsb to raise t e desired type levers etc., upwardly as determined by the depressed keys, as hereinafter described; and when the operating crank D is released, the main springs C cause a reverse movement of the above described mechanism. 2-

The type hammer consists of a bar E (see Fig. 1) supported upon swinging levers E, E which are pivoted between upright supports E secured upon the base of the machine, upon a pivot shaft 6, said levers E being provided with retracting springs 6 (see Fig. 6) to furnish the necessary motive force for the hammer strokes. To retain the hammer in its striking position as shown in Fig. 6, aspring actuated latch-hook E is pivoted to one'of the supports E which an gages one of the levers E. For releasing the latch-hoo i from engagement with the lever E, I provide the lever 01 with an arm d which, when the lever d swings forward during the above described operation of the actuating mechanism, is adapted to strike the latch-hook mechanism E and cause the same to release the lever E and leave it free i to the action of the spring e. on the return of the actuating mechanism to its normal position the lever d secured on the shaft d, engages the hammer-lever E" and pushes it backward until the latch-hook E again engages it.

It is obvious from an inspection of Fig. 6, that the arm d of the lever 02 will not engage the latch-hook E until the lever 03 has about completed its forward movement, so that the type-carriers :b will have raised the desired typesto the printing'line in frontof the platen-roller b Tbefoi-e the hammer is released.

Controlling or Selective mechanism.

This mechanism consists of'the vertically movable rack-gears F,F, F F ,'F*, F and F (see Figs. 6, 8 and 9 which are slidably mounted'o'n slides f secured in .the base. A of the machine, and the cross-bar f supported on the frame plates A, to which cross bar the upper ends of the individual springs 11" are also secured;

These rack-gears F, etc., have each two rows of teeth f v and, f which are spaced apart, as shown in Fig 8, but on different vertical. planes, as shown in Figs. 9 and 24. The racks F, etc., are also provided with flanges f and f at the lower and upper ends of their rear sides, and slidably securedon the rear sides of the racks F, etc., are plates G which are shorter than the space between the flanges f and f so as to permit suflicient relative movement of said racks and plates for the purpose hereinafter described.

The plates G are provided with ears Ur (see Figs. 6 and 2l)'which are connected to the type levers by means of links 9, so that the levers B, B", etc., plates G, and racks F, etc., will move-in unison. The individual springszb' are connected to the ears G of the plates G, and a short spring I) extends from a post f (see Figs 20, 22 and 24) extending; through a slot in the plates G and secured in the racks F, etc., and acts to yieldingly maintain the flanges f on the racks F, etc., against the lower ends of the plates G. These plates G control the printing of the zeros, and also provide for the carrying over from a lower order to the next higher order.

Slidably and rotatably mounted in transverse bars H H are rotatable members consisting preferably of shafts H, H H, H,

H H and H, each; of which is provided with a series of nine radial detents or posts It, lon itudin'ally arranged around its periphery. iEach shaft H, etc, has secured lll' leliwon a gear pinion J (see Figs. 8 and 9) which intermesh normally with the racloteeth f on the racks F, etc.,- so that when; any of said racks move upward the shafts geared thereto are caused torotate.

Rack-locking meckanisip.

In order to prevent. the movement of the racks F, etc-., and the-plates Gthereon,. so that'zeroswill notbe-printeds tofftheleft of numerals, I provideon the: racks F, etc, arms f, and on the plate G, arms-g (see Figs. 9, 21. 22 M241). Upon a transverse baxr- K. in. the. machine frame; are slidabliy mounted locking devices consisting of elond .U-shaped. slides; K. K K*,.-ete.,, (see igs. 8, 9: and 9'-A.') within whinhaupon the bartK are slideble blockshk, k?,.etc-.,.of less Iength-wthan the space betwesm the. aims of the U-shaped slides. i i

Above the bar K is a slidable sprin pressed bar E (see Figs. 6, 7 and 8) to which springs L" are attached, which extend and: are at tachedi to the slides K, K, e120,. (see- Figs; 8, 9 and Q-Ai): andto thevslides lo,.-] ,-etc., so thatwhenthe banhiszmoved. to the .le-tt. said springs Iufi dzaw' the slides K,.etc., and the slides -k,.etc., towaadiflhealefti Inn order"tocause'theslidesKQem, and: 70, etc, to return to their nnrmal position, the slidable; bar; L. isuprovideduwith. arms Z, Z ete.,..which; ontheir movement toward the right engage projeiotin'gfstludsk on the slides k,.k, etc, and force. all of said! slides to the right. or' their nonmah positions. The slides 16,. k.

If noxkeys are depresed; and the operatr ing lever-D isoperated', the sliding bar D will be moved towand the left and will, through the springslli." draw the outer U shapedv slides K, K, K ,.etc.,to-the 1eft in unison until't'he last slide 10 contacts-withr the side plate ofthemachine frame A, the distance of said\mov-emelrt being. two'spaces.

The-inner slides lo k, 10*, etc.,.whicli carry the arms or projections: 15 2, 3, etc, move with the outen U 'shaped slides until the movement of said outer slides is stopped when the inner slides continue to movetoward the'left' one more spaceuntil they contact: with the left hand arms of. the U- shaped slides; said innen slidesthus moving a distance of three spaces, which carries their arm 1, 2, 3, etc, over the rack-arms f and the plate-arms 9' so that neither racks nor plates are permitted to move upward, being by said arms 1, 2, 3, etc, securely locked in their most downward position.

If-hmvever, a'key is depressed, as shown in Fig. 10, the inner slide- It will cause-the key-locking. bar It to swing into the notch n in the key-lever N (see Fig. 10) and thereby stop the left hand movement of the inner slide k at'th'e end of one space, as shown in Fig. 8'; and also the"l-i-ke movement of the U-shaped slides K and I withthe arm l on the inner slide 1.: having moved two spaces and overlapping the arm f" on the rack F, and the arm'Q on the inner" slide is having n'ow' moved but one space dloesnot overlap the arm f" on the -rack"F, whi-le thou-shaped slides K",l K etc, movetwe spaces andthei'r inner slides k it, etc, are permitted to move toward the left three-spaces-so'that the armsfi, 4, 5; etci, on the inner slides It, k etc, overlap both arms f and g ongthe racks andslideplates so that" said racks and plates are thereby prevented from moving upward during the printing ofthe desired amount by the first and second order type carriers. v The operation SofIthe'mechaniSm' ahovedescribed is fu rther describedunder? the head of Adding operation commencing on page 9. r

Keyrb oard mechanism.

In constructing the key-board mechanism ofmy machine-I provide a frame composed ofthe' side-bars M M (see Figs. 10, 11' and 12) upon which is placed a top-plate M" through which'the'lrey-st'ems O operate. I also provide transverse barsM M which enter notches cut= inthe'upper edgeof the the detents h on the shafts H, H, etc.,

when the keys are depressed and the shafts are rotated as hereinbefore described, for the purpose of stopping said rotation at the desired point. i v r The key-levers .N are also provided with notches n into which the locking-bars h enter when a key is depressed,'as shown in- Fig. 10, and the operating lever D is operated the locking-bars to the left of the de-;

pressed key'moving upward so as to cometo rest underthe'key-leverswN to -the right and left of the depressed key when the actuating mechanism is operated, thus prerenting the depressing of any keys after the initial movement of said actuating mechanism.

For retaining the keys in a depressed" position prior tothe operation of theactuating mechanism'I pivot in the keyboard" frame, spring-pressed bars "0' which are parallel with each column of keysfrom the lowest order to the highest, said bars 0" being adapted to engage the shoulders n on the l-;eylcvers N when the keys are depressed, so as to retain the keys in a dcpressed position until released at the end of the operation of the actuating mechanism, as hereinafter explained. 7

These spring-pressed bars 0 also nor'- mally engage notches n on the hey-let ers N when'they return to their normal raised position. F or disengaging the bars 0 from the depressed key-levers N to permit the keys to return to their normal position, I provide a transverselyslidable spring prcssed bar P (see Fig. 1) which is provided with studs 7) adapted to engage each bar 0' and force them out of engagement with the shoulders n on the hey-levers,

when the bar P is'moved to the right. Foroperating the bar P I provide. a lever P" (see Figs. 1 and 7) which is pivoted upon a bracket 11' on the side frame'A'. onearm of said lever being pivoted to said bar P. The opposite arm of said lever is provided with a hinged joint P and theextremity of the hinged arm is provided with an inclined surface 72 which is engaged by a lever D* on the actuating shaft D for the purpose of forcing the.hinged portion of the lever P upward so that it will pass under said lever during its forward movement. The hinged arm of the lever P is notches n on the key-levers N.-

also provided with a cam-surface P (see Fig. 1) which the lever D"(see Fig. 7)

engages on the last portion of the reverse inovementof the actuating shaft D, and

causes the lever 1 to movethe bar P to the -right,thus bringin the studs p against the locking-bars 0' an off of the shoulder n on the key-levers N of the depressed keys, and allowing the springs N (see Fig.

The shifting oh the accumulator mechanism to the position shown in Fig. 13, causes the ri .S' :to operate the springpressed bolt U upon the supposition that a number is thereon accumulated; but if any particular accumuiatorstnnds ;at zero,-tho notch s on the ring S .will 'registerwith the spring-pressed bolt U, and said bolt U will enter said notch and .will not be operated by said ring. I

The operation of the sprm -pressed bolts U stops the movement-of the locking-bars h at the endof one spaceythe same as -a depressed key would stop th em, said lockingbars h stoppin the left hand movement-of the inner slides k,-etc., so that the racks F mule-tors, of the items previously listed.

The vkey 16 when pressed down, is held clown until the 'actuatin shaft is started, which, thro'u h the slidear L (see Fig. 8) causes the sli e k to o eratethelocking-har It, which engages note as 30 in, the sides of the stem of the key 16, saidlocking-hars Jr. bein moved. backward from said key-stem on t e reverse movement of the actuating shaft D.

To cause the sliding-bar L to reciprocate when the 'shaft D is rocked, I jivot on the side frame-plate A a. segmenta cam '31 by means of a. pivotpost 32, and I put a crankarm 33 on the shaft D which is connected Total recording mechanism To record the final total of the listed items, after which the accumulators will all be re turned to zero, I provide a key-stem 36 which is adapted to engage the lever X and swing it downwardly to the positionthereof shown by broken lines in Fig. 2-A, in which position it must be retained by the finger of the opcmtor until the actuating mechanism is started. when the locking-bar it (see Fig. 8) will be swung over to engage the notch 37 in the key-stem,to hold the key-stem 36 in its depressed position The downward movement of the lever X causes the lever X to move in unison therewith and withdrew the post X (see Fig. 2) from behind the slide 7 so that the lever K (see Fig. 2-A) acting against the arm 19 can move the slide-bar 23 and lever V toward the rear of the machine, thus shifting the accumulator mechanism to the position shown in Fig. 13. f

\Vhen the lrey-stem 36 is depressed, the L-shaped lever-bar 38 pivoted theretoend to the side frame A (see Fi 2-A) is moved to the position thereof shown by broken lines in said :Fig. 2-A, so that the eamsurfece 39 on the side of the segmental plate 40 will engage said L shaped lever-bar 38' arm 42 of the lever 17 and the cam surface 40 (see Fig. 2-A) will engage said lever arm 42 and cause'it to move-the 'arm 19 downwardly so that the point on the upper end of the leVer' Xwill enter the notch 20 cutout of the upper end of the arm 19, and permit the slide-bar 23-and levers Land accumulator mechanism Q. to be-m0ved back to their normalengaged position, as shown in Fig. 15, by the centralizing mechanism Y, etc, shown in Fig. l

I The movement of the slide-bar 23 toward the rear of themachine, as above described, hasswung the levers 28 to'the position thereof shown by. broken lines in Fig; 'Q-A, and niovedthe detent shaftsH em, to -the rear, as in the sub-total bperation hereinbeforedescribed, and the latch-arm '43 has droppeddowntoenga'ge the stud pin 44 on the lever 28, thus retaining the levers28 and detentshafts H, etc., in th'eir rearwardl hift d po iti z m u, i; 1:; umo: In uisi or" On the reverse movement of the actuating shaft D and segmental plate W (see Fig. 2) the spring to moves the slide W rearwardly, the slide W being held-stationary by the centralizing mechanism Y, etc., shown in .--Fi 7, the rearward movement of the bar 'W causing the stud-pin 45 secured thereon (see Fig.2-A) 'to engage an arm on-the latch" 43and -swing said latch up wardly to disengage the samefrom the studpin 44 on the lever 28,-which permits the spring 46 (see Fig.1) to shift the detent shafts H, etc., back to their normal position, as-shown in Fig. 2:

During the reverse'imovement 'of the actuating shaft D, the main springs C are gradually released so that the racks F, etc, are caused to-return to their normal positions, thus causing the detent' shafts and accumulator mechanisms operated by said shafts to return to their normal zero positions, and at the termination of the reverse movement of the shaft D the detent shafts H, etc, are returned to their normal positions, as described.

Subtracting mechanism.

In order that the machine will deduct an amount listed from the preceding items, I provide a bell-crank" lever 47 which is pivoted on the frame plate A by means of the pivot 48. One arm of this lever l7 engages the stud 49 on the lever 28, and the other arm is pivoted to the key-stem 50 of the subtracting key. \Vhen the key-stem 50 is depressed, the bell-crank lever 47 engaging the stud 49 swin s the levers 28, which causes the detent shafts H, etc, to slide rearwardly, shifting the pinion-gears J out of mesh with the gear rack f and into mesh with the gear rack f the square stud on the accumulator shaft '1 which extends into the square opening it in the end of the shafts H, etc., permitting of said edgewise movement of said shafts.

hen the key-stem 50 is depressed as above described, the accumulator mechanism is not shiftech Now, when the actuating shaft is operated to record the amount to be deducted,' the racks F etc., cause the detent shafts-to rotate toward the left, or in reverse direction to the adding or" normal rotation of said detent shafts, which I'VBIS ing of the detent shafts causes the accumulator mechanism torotate backward the requirednumber of units.

During this subtracting operation the latch 43 operates and is released exactly as in-the sub-total and total operations.

1 .Repeating mechanism.

In order to enable the machine to repeat the operation of printing and adding the same amount at *each successive operation ofthe' 'actuating mechanism without further manipulation of'the finger-keys, I 'provide a key-operated lever 51, which is provided with a key-stem 52 which has a shoulder 53 adapted to engage a stud 58 secured on the side of the'casing 54 of the machine, when the-key stem 52 is depressed. A spring 55 is also-provided, one end of which is secured to a stud 56 on the casing of the machine, and the other end of which is secured to a post '57 on the key-stem, so that said spring not only lifts the key-stem upwardly, but throws-'the'same toward'the left so that the shoulder 53 will engage the stud 58 and retain the key-stem 52 inf1ts depressed position. 1

When the lever 51 is operated, it raises the hinged end of the lever P so that it will not 'be'engaged 'bythe-cam-arm D, and the said lever P will not be operated to actuate the slide-bar P to disen age the dog-bars 0 from the. key-levers I\, so that when the required keys are depressed to record and add a certain amount, to repeat said amount the key-actuated lever 51 is depressed, and the actuating lever D is operated the number of times it is desired to repeat the recording and adding of said given number.

On the final operation of the lever D the locking mechanism of said key-actuated lever 51 is released so that the hinged end of the lever P will engage the cam-arm D, to be operated thereby to cause the disengagement of the locking-bars 0 from the depressed key-levers N.

Adding operation.

Wvhen it is desired to add 50 and 60, the 5 key in the second order row from the right is depressed, which causes the key lever N (see Fig. 10) connected with said key, to move to the position shown in said figure. The actuating arm D is then moved downward. At the commencement of the movement (at the. handle D,,thearm D on the actuating shaft D causes the crank-arm d to swing the arm C from. the dead center position shown in Fig. 6, downwand. Atv the commencement of the swing of the arm C downward, there is little if any longitudhialmonement imparted to the rods. 0 and cross-ban C, so. that practically there is an.. appreciable degree. of lost. motion during thefirst portionof-the forward swing at the actuating; arm- D, as shown in. El 6, during; which timethei segmental plate (see Fig. 2) rotates-totheright. and

the upper end of, thev bell-crank letter -W".

is. actuated by the. cam,-surf ace-W to. cause the slide-bars. W and W tomono, toward the right as hereinbefore described for the purpose of disengaging the accumulator mechanism. Q as hereinbefulieldeseribedh.

The continued ferw ,d movement, if actuating, lever. u dnaws ,theg enoss bar. C away firom. the arm; 12 .ottha typevlevers B", BF, etc, which permits them t hesw-uh upwardly ontheirpivot.

The locking. bars 1&3 are operated by. and

The uvshaped slide of the. second, order K also=has been moved to the left until its right hand: arm engages; the inner slide is and is stopped thereby at the end of a onespace movement.

The outer U-shaped. slide K of the first order also moves towardithe left in unison with the second order U-shaped slide and is stopped thereby at'the end' of a one-space movement, while the inner slide hmoves to the left with its outer slide one space and then continues to move to the left one space more until it isstopped by contact with the lefthand arm of its U-shapedslide K, so that-said inneizslide in. has, moved toward the left. two spaces, which carries the arm Z on. said inner slide over the: rack-arm f and thereby prevents the first order rack firom moving upward. The arm g of the slide plate G on said rack not being overlapped by said arm Z is permitted to move upward until stopped by the flange thus allowing the right hand type lever to elevate its type-carriersufliciently to bring a. zenotype to, the printing-line. beside the 5 type on the next higher order; type carried The slides k k is, k and 7c are also simultaneously moved toward therleft far enough behave theirarms 3,. 4', and 5 overlap the arm i on; the racks F -F F and F and to overlap-the armsvg on;. the; plates-G slidable on said racks, soithat-i-noneofi said racks andplates can. move when-the printing mechanism isactuated, which prevents.- the printing; of. zeros tothe left. of. the. lett hand num r a I The-eross arms T at said accumulator mechanism rotate in unisonwithlthedetent shafts HQ, ete untili the shatt H stopped by. the, detent h representing thenumeral 5, engages the depressed -hey-lever N as shown in,Fig-, '10, and when the segmental plate llfi engages the leuerf-X (,see Figs. 2,. 2-B., and 2 C) said lever X withdraws the upright post X from behind theslidebar; which, permits the centralizing mechanism; Y.',.etc., to'sh'ift the accumulating mechanism to the position. shown in Fig. 15, so thatthe cross-bars T will engage internal teeth a in the ring- S representing 5 and onthe returnmovement of the actual:- ing lever D the main springs are permitted to. drawthe type-leversB and racks F, F do i\'n'ward,lthus rotating-the detent shafts to the left and hack to their normal position; the crossrarms T rotating the accumulators Q forward- 5 points. and: displaying; 50' on the wheel Q in the firstand second orders.

On-theforward movement of the actuating handle D, thearm- D on. the shaft D passes under the hinged end of the lever P (see Fig. 7), and on the reverse movement of the actuating handleDWsaid-arm D engages the cam-surface P (ls ee Fig. 1) on the hinged end of the l'ever and operates said lever to move the slide-bar P toward the right so that the stud; p thereon will engage the; dog-bars 0 (see Fig. 10) and swing them out of. engagement with the depressed key levers N and allow them to return to. their normal raised, position.

To ensure themechanism against careless manipulation of the key mechanism after the actuati ;mecha.nismis started in operation, the slides: in, k, etc, swing the lockingbars it (see Figs. 8 and 10) upward so that the same will enter the notches n in the depressed key'levers N and pass under these key-levers N which are not depressed, so that it is impossible to depress a. key duringthe operation of the actuating mechanism.

Next the key representing 6 in the second order is depressed, which-swings the keylever N downward so that it will engage the detent h on the shaft H corresponding to 6. The actuating mechanism is again operated as before, whereupon the different mechanisms function as described in relation tothe printing ofthe'iirst item, except that the accumulator wheel Q- 'of the second order revolvesjfar enough to display a:l, and'in so doing the cam'rg thereon operates the arm aof the bell-cranklever Z (see Fig. 5). and causes the slide-bar Z to withdraw its wedge-shaped shoulder 2? (see Fig. 6) from under the rackv F thus permitting it to'dropdowns sufiicient distanoe to .rotate the detent, shaft H one point, which causestheacriumulator wheel Q, of. the third orderto rotate-,in'unison therewith one point and, display; ,gthfl? nu; meral 1, thus showing :itllfi sum 1Ofn110.

,S'ubtmct ing operation.

We will now, subtract 11. The ,lreys 11 in the first and second orders are depressed, and the subtracting key 19 is depressed, which shifts the detent shafts H, etc., rearwardly, carrying therewith the pinion gears J from mesh with the rack-teeth 7' into mesh with the rack-teeth f (see Fig. 9). The actuating mechanism is then operated, which permits the elevation of the racks'F and F so that the type 1 of the first and second order are raised to the printing line, and the detent shafts are reversely rotated toward the left until the 1 detents h thereon engage the depressed key-levers N.

Upon the return movement of the actuating handle D a reverse motion is communicated to the accumulator wheels by the shafts H etc, as follows:

The first order accumulator wheel Q, is turned backward through its associated detent shaft H to display the numeral 9, thereby causing the cam g thereon to withdraw the bar Z from under the second order rack F. The second order rack, thereupon, moves downward and rests upon the baseplate, said movement representing the 1 plus the carry-over, equaling two units, thereby revolving the detent shaft H of the second order, which revolves the second order -accumulator- :wheel5 Q backwards to display th'eJnurneral-S). This causes the cam on.;theoisecondforder accumulator Q, to

withdrawthe slide-bartZ -of the third order from under the third orderraclol", thus allowing said raclc:-to,dr0p down upon the base-plate: which causes Ethe: detent shaft H of'the-jthird ordergtoturn'its' associated accumulator wheel backward one unit to dis- :play; a) ZBLOq-y- The accumulator wheels new display airemainderof99 .26 tal f ii'perdtion.
